Superconducting Magnetic Energy Storage: Status and
Abstract — The SMES (Superconducting Magnetic Energy Storage) is one of the very few direct electric energy storage systems. Its energy density is limited by mechanical considerations to
6 FAQs about [Coil energy storage circuit protection]
What is superconducting magnetic energy storage (SMES)?
Superconducting magnetic energy storage (SMES) systems store energy in the magnetic field created by the flow of direct current in a superconducting coil that has been cryogenically cooled to a temperature below its superconducting critical temperature. This use of superconducting coils to store magnetic energy was invented by M. Ferrier in 1970.
How does a superconducting coil work?
Once the superconducting coil is charged, the DC in the coil will continuously run without any energy loss, allowing the energy to be perfectly stored indefinitely until the SMES system is intentionally discharged. This high efficiency allows SMES systems to boast end-to-end efficiencies of over 95%.
How long does a superconducting coil last?
As a result, superconducting coil can persist current or energy (1/2 LI 2) for years with energy density as high as 100 MJ/m 3. Though, it charges and discharges very quickly, its discharging time is faster than charging.
What happens if a superconducting coil reaches a critical field?
Above a certain field strength, known as the critical field, the superconducting state is destroyed. This means that there exists a maximum charging rate for the superconducting material, given that the magnitude of the magnetic field determines the flux captured by the superconducting coil.
Does a superconducting coil have a maximum charging rate?
This means that there exists a maximum charging rate for the superconducting material, given that the magnitude of the magnetic field determines the flux captured by the superconducting coil. In general power systems look to maximize the current they are able to handle.
Are superconducting tapes a good choice for SMEs coils?
With the improvement of superconducting tapes from LTS to HTS technology, the effectiveness of SMES is also increased. Though HTS wire is very expensive and required in large quantities for SMES coil, it is still cost effective from power system stability and inexpensive liquid nitrogen refrigeration points of view.
